When getting low in stock, how do you change the text colour?

Hi!

Great plugin is pretty much what i need! but wondering if it can do the following, or if it already can but doing it incorrectly.

Is it possible so when you have loads of products in stock, say 20, it says 20 in stock in green. (which it already does)

When the stock gets to a low amount like 7, the text turns orange and says 7 in stock, more coming soon. (cant get to work, or doesn’t exist)

Then when out of stock, it just goes Red saying Out OF stock. (which it already does)

There is an option on the settings saying “Only %s left in stock” but i cant get this to do anything.

Thanks for help!
